STAMP-AFFIXING Arramrus,

Application fil ed. March 29, 1926. Serial No. 98,155.

My invention relates to stamp aifixing and sealing apparatus. And an object of my improvements is to provide an improved apparatusfor placingstamps upon folders and {thereby securing the detached edges of the folder together for mailing. I secure this object in thegapparatusillustrated in the accompanying drawingsin which:

Figure 1, is a plan view of a ,stampa'flix- 10 ing machine with apparatus embodying my inventionattached thereto.

Figure 2, is aside elevation tovan enlarged scale of a portion of the machine and apparatus shown inFig. 1. i I

Figure 3, is a section on the line III, III, of Fig. 2. y

Figure 4, is a detailed section in the plane indicated by the line IV, IV Fig. 2.

Figure 5, is a section on the line V. V. Fig. 1. i

A Figure 7, is a perspective View looking from beneath Fig. 6.

Figure 8, is a perspective view of the rollers, carrier and guides therefor, by which rollers the stamp upon the folder is held during the turning over of the protrudin portion thereof.

Figure 9, is a perspective view of a portion of the edge of a folder with the stamp allixed ready to be turned over upon the other outer surface of the folder to secure the detached edges of the folder together.

- Figure 9, is. a detailed sectional view showing the stamp and adjacent parts of the ap-' paratus when the stamps are just beginning to be turned over. v

Figure 10, is a view similar to Figure 9 the stamp being turned tov a greater degree.

Figure 11, is a view similar to Figures 9 and 10, the stamp being completely turned over.

Figure 12, is a detailed section in the plane XII-XII, Fig.8. f

Figure 13, is a perspective View of the folder with the stamp aflixed thereto in position to hold the detached edges of the folder together for mailing.

I have represented my improved apparatus in connection with a stamp afiixing machine of the type known as Mail-O- Meter, and this is adjusted to aflix the stamp to one surface of the folder at the center,"

a portion of the stamp protruding beyond the folder where the edges thereof are, de-

tached,as described in the co-pending appliare the i The folder is fed to the machine at the left of Fig. 1, with the edges that are detached upward has the stamp affixed thereto 7 in the usualaway, except that about half of the stamp protrudes beyond the upper edge of the folder, passes between the pairs of rollers 0,6, and c and is'stached upon the table 7'. While thus passing through the machine the protruding portion of the stamp is turned over upon the other surface of the folder and is caused to adhere thereto so as to join said edges and seal the folder by an apparatus described as follows:

'g, is a shoemade of sheet metal, or other suitable material placed, with itsaxis approximately horizontal, between the pairs of rollers a-a, and b-b. The shoe g, is ap proximately conical in shape with its lower portion open, as illustrated in Figures 6 and 7. The larger end of the shoe is adjacent to the rollers a-w and positioned to receive and engage the protruding of the stamp, as shown in Fig.9.

n and are stationary portions of the machine frame,

g is a Z-shaped piece of springv metal sea cured to the smaller end of the shoe 9 at one end and adjustably securedin a slot 9 in the frame part n by a screw 9.

g, is an elastic arm one end of which is secured to the largerend of the shoe 9 and the other end is adjustably attached to the frame part of, by a screw 9 passing through the slot 9 It, is a socket piece fixed to the frame of the machine with its open end just below the shoe I k b are the upper and lower sides of the socket h. i

j, is a carrier having avertical inner por tion j and horizontal upper-and lower portions j -j. (Fig. 8.) g V j", is a series of rollers pivoted vertically between the upper and lower portions :7' of the -arrier j. ltj, are springs interposed between the back of the socket piece It and the rear of the carrier j and adapted to press said carrier outward and the rollersagainst the stamps on the passing folder. The rollers j are of such a size that one is always in engagement with the stamp when itis passing through the shoe 9 and thereby the attached portion of the Stamp is held in contact with the folder so that the turning over of the protruding portion shall notdetach the attached portion.

The operation of the above described apparatus is as follows:

The folders are fed to the machine from the left of Fig. 1, have the stamps afiixed thereto with their upper ends protruding above the edge of the folder, as shown in Figure 9 and pass between the rollers (La and are fed betwcenagu'ide a and the rollers 9''. During which passage the protruding portion of the stamp is turned over by the shoe g, as shown in Figures9, 10, and 11 and is fixed to both surfaces of the folder 122 securing the detached edges together, as shown in Fig. 13. The folders are then fed forward through and between the rollers b-b and cc which causes the turned over portion of the stamp to adhere firmly to the opposite surface of the folder.

What I "claim is:

1. In combination with a stamping machine adapted to aflix a stamp to mail matter with a portion of the stamp protruding beyond the edge thereof and to cause the mail matter to be carried theretl'irough, an apparatus interposed in the line of travel of said mail matter through the machine, adapted to turn the protruding portion of the stamp over upon the surface of the mail matter and mechanical means for holding the portion of the stamp attached to the folder in contact therewith while the protruding portion of the stamp is being turned over.

2. In combination with a stamping machine adapted to affix a stainp to mail matter with a portion of the stamp protruding beyond the edge thereof and to cause the mail matter to be carried therethrough, an apparatus interposed in the line of travel of said mail matter through the machine. adapted to turn the protruding portion of the stamp over upon the surface of the mail matter and mechanical means for holding the portion of the stamp attached to the folder in contact therewith while the protruding portion of the stamp is'being turned over, said mechanical means consisting of a series of small rollers yieldingly pressing against the detached portion of the stamp.

In testimony whereof, I sign this specification.

ROBERT S. MURPHY.
